Warning!
Electrical installation should be done by qualified technician only.
Before connecting to AC Power Source, turn power switch to OFF

switch and automatic operation switch to off.
1.4.1 Safety Regulations for the Blowers
1) Under normal operation, the blowers will generate high temperature. Do
not touch blower's case to avoid any physical injury.
2) Under normal operation, the blower motor's current loading will increase or
reduce according to air pressure's change accordingly. While installation,
an adequate motor overload protection switch should be installed with full
loading test, to ensure operating safely under full-loading to avoid motor's
damage.
3) To avoid any block materials, dust, powder, fiber particles and water drops
entering the blower, and hence cause the deficiency of its performance.
This machine is well designed with air filters, so please clean up the filter
with any foreign particles (recommended to clean up this filter weekly).
4) Clean the blowers both internal and external parts (especially for the fan
cooling path), and remove surface dust if necessary. If more dusts are
accumulated, it will cause deficiency for ventilation, temperature rising,
vacuum power reduced, vibration increased and so it will cause machine
broke down.
5) Ball bearing, oil seal and soundproof are belonging to consumable parts
and so it has a life period and requires regular replacement. Meanwhile,
blade, external case, and metallic screen etc. should be replaced regularly
for best performance.
6) Under normal operation, if the blowers are not running smoothly or
abnormal noise appeared. Please immediately shut down the machine for
